T 0 all whom it may concern:

B it known that I, LEWIS E. Warnnrmri, a citizen or" the United States,residing at Rockford, in the county of Winnebago and invented. certainnew and useful Improvements in Revolvinglian rows, of which thefollowing is a specification.

The object of this invention is to provide gang sections of a revolvingharrow, and conto the support. the driver seated therein can with hisfeet reach the foot-levers 13 and 1 1.

A seat support 18 is secured to the rear end f the tongue 5, and a seat19 is connected The seat is so located that When the parts are in theposition shown at Fig. 2, the dogs 11 and 17 rest against the teeth ofthe toothed segment 9. down on the foot lever 14, the dog 17 restingagainst a tooth will act force the upper end of the rock-bar ahead Bypressing as a fulcrum and nections whereby the team may straightencarrying the dog with it until the dog 11 the sections or place them 1nalinement. drops into another notch ahead, which Wlll In theaccompanying drawings, Fi ure 1 of a revolving harrow containing myimprovements. Fig. 2 is a vertical transverse section through one of thegangs, the frame and parts supported thereby not sectioned. Fig. 3 is anelevation of the lation to one another.

The revolving harrow herein shown, in the main is of a well knownconstruction and comprises the two gang sections 1 and 2 sup 3, by theconnecting bars 4. These bars form a pivotal connection between the mainframe and gang sections. A tongue 5 is supported by the main frame. Arock-bar is pivotally supported and to its lower end 6 are pivoted twobars 7, the rear ends of vhich have the usual connections with the innerends of the gang sections. To the lower portion 6 of this rock-barpivoted a draft atin the lengthwise direction. of the rock-bar.

To the tongue 5 is secured a toothed segment 9, and adjacent to which islocated the upper portion 10 of the roclehar. To the prevent therock-bar moving rearward. Upon releasing the foot-lever 14 the spring 16will raise the foot-lever 14 and carry the dog 17 another notch ahead.ment of the foot-lever 14 will move the rockbar ahead until the dog 11is in the forward notch which will move the lower end 6 of the rock-barrearward, thereby moving the inner ends of the gang sections rearwardinto working position. 7 can be adjusted with relation to one another toangle the toothed heads more or less across the line of draft ascircumstances may require. the foot-lever 13 and moving it forward, thedog 11 will be disengaged from the teeth of the toothed segment 9, andby further dcpressing the foot-lever 13, the dog will ongage the dog 17and raise it free of the toothed segment, and hold it in this position.The team by pulling on the clevis 8 will move the rock-bar on itspivotal support which, through the bars 7 will move the gang sectionsinto alinement as shown at Fig. 1.

Tothe upper end 10 of the rock-bar and nvoted, is pivoted a foot-lever14 having an upturned end 15, and a spring 16' is located between thisupturned end 15 and the foot-lever 13.

To the foot-lever 1 1 is pivoted a dog 17, the free end of "\vl'iich isadapted to engage the teeth of the toothed segment 9. The dog 11 is alsoadapted to engage the teeth of the toothed segment 9.
